Emilio De Fabris (28 October 1808 – 3 June 1883) was an Italian architect best known for his design of the west facade of Santa Maria del Fiore, Florence.
In 1857–1860, he helped design, alongside Michelangelo Maiorfi, the Palazzo della Borsa in Florence.
He was professor at the Florentine Academy of Fine Arts and Architect to the Opera di Santa Croce.
The original facade design for Santa Maria del Fiore, by Giotto, was found outdated for the cathedral and so a series of three competitions was held to modify Giotto's original design, keeping with the main lines of the structure.
In 1871, Fabris' design won, and he immediately went to work embellishing the cathedral with red, green, and white marble.
